lie itknown that 1. ltn'tuoxn lil'ltXiLUf. a eitixen ot' the l'nited States. residing at Minneapolis, in the eounty ot' llennepin and State of .\l.inuesota. have invented eertain new and useful Improvements in Magnetie lingiues. of whieh the following is a speeiiieutiou.

My invention relates to magnetie engines and is a division of my eo-pmiding applieation tiled .\'ovemher :11, 19M. Serial No.

low-2o.

The invention has for its primary ohjeet the provision of an improved magnetic engiue. whieh shall have improved means for eausing me hanism without a sealed ehamher tohe aetuated hy movable partstherewithin.

'ith the aliove and other ohjeets in view this invention eonsists suhstantially in the eomhinatiou. arrangement. and eoustruetion of parts all as hereinafter deserihed. shown in the aeeompauying drawings whieh t'orm a, part of this speeilieation. and more speeitieally set forth in the suhjoined elaims.

1n thedrawings: Figure 1 is a ertieal sertion of my invention taken approximately on the line 1-1 oi Fig. 3. looking in the direetion indieated hy the arrows. and showing it-applied to a steam-meter. Fig. .2 is a front elevation of my invention with a part. of the dial hrolten away and showing it in eonihination with a steam meter. Fig. 3 is a horizontal section taken approxi mately on the line 3-3 oi Fig. :2 looking in the direetiou indieated hy the arrows. and showing it in eomhination with a steam meter.

1n the present exeniplil ieation of my. invention it is illustrated as aetnated by a steam meter whieh is operated hy a steam pipe 1 and attaehed to the steam pipe by means of hushings 2 aml i. and the invention 1 is further illustrated as adapted to the driv ing of an indieator arm about a dial. although it may he used in many other-ways. A litot tuhe eomprising a neek 4 and an elhow 5. is seeured within the hashing .2 and. has its mouth turned against the eurrent of steam in the pi; 1. The neek 4 of the litot. tube eommunieates with the lloat ehamher 6, containing water of emulensation. An arm 8 pivoted intermediate its extremities to a support 9 is operatively connected at a magnet 11 pivoted in the ehamher 12 upon a shaft 15. The eham'ier 12 is preferably provided with-a steam-tight eap '16 whereby across may he had to the parts within the ehamher 1:2 and. if it he found convenient, the rap may he reeessed as at 17 to form a hearing for one end of the shaft 15, the other end of the shaft lfiheing preferably pointed and supported in the opposite wall of the ehamher 12. as shown in Fig. 3. other forms of eonstruetion may obviously he employed for operatively eonneeting the magnet 14 with the float 7 so as to more the magnet. when the float moves. .The rotation of the magnet 14 (tier-ts a eorresponding rotation of a magnet 13 mounted outside the ehamher 1:2 and near enough to the casing to he within the magnetic influenee or field of the magnet 14. the two magnets being preferablyarranged to rotate in parallel planes. The magnet 15 is mounted upon an arbor 1 one end of whieh is supported in a wall of the ehamher 1'2 and the other end in a lu'aeket 2t). gear wheel :21.

pinion 3:2 inmesh with the gear wheel 21,

the pinion heing eonsiderahly smaller than the gear wheel 21. and the arhor 9.3 being journaled at one of its ends in the wall of the ehamher 1:2 and at its other end in the hraeket 2t). dial ease '27 is positioned'adjaeent the ehamher 1'2 and through its hack plate :24 the outer end of the arhor 23 projeets. Au indieator arm '25 is earrieil l iy'the projeeting end of the arhol"23:and is positioned to register with various gradnations flli'upon a dial 2?. contained in the dial chse :27. From this (leseription it will he seen that a very slight movement of the til'mt 7 will he magnified through the =gear=21 and the pinion ".22 into a relatively-large"move ment of the indieatoiyarm 25. In-this manner a readable indieation ofthe slightest; movement of the float T is exhibited upon the dial 27. Various: meehanisms other than the multiplying gear and indicating apparatus just described may, of course, be driven by the magnetic engine.

The upper part of the float chamber 6 is connected with the steam pipe 1. The end of this upper passage includes a piece of tubing 28 positioned in the bushing 3, pro-' These latter are shown as connected respectively by tubes 33 and 34 with the upper and lower inlets of the float chamber 6.

If desired a condensation coil 35 may be inserted with its extremities connected to the .tubes 33 and 34, as shown in Fig. 1. An automatic air relief may be, provided communicating with the chamber 6, and access to the chamber 6 is rovided by means of plugs 37 and 38.

The steam meter is shown and described in the drawings for the purpose of illustrating my invention operatively connected to a medium whose variations are to be'indicated', but it is not intended to restrict the use of my magnetic engine to combination with a steam meter, it being obvious fromthe fore- 3 going description that it'may be used in combination with a great number of other mechanisms. Neither is it intended to restrict the use of my magnetic engine to the operationof a magnetic indicator, for it may be 'operatively connected to a variety ofother devices. 4

.In the accompanying drawings 'and'in the foregoing description is set forth the preferred gmbodiment of myinvention, but it 1: is obvious that-one skilled in the art may modify it without departing from the principle'thereof. g

I claim:

. 1-. The combination'with a float chamber,

5 of a pivotally mounted float therein, a movable magnet connected with the float, an auxiliary chamber inclosingsaidmagnet and in communication withiv said float chamber though hermetically. sealed from the atmosphereyand a second m'agnetoutside of said auxiliary chamberbut within the magnetic field ofasaid first-named magnet formove-- Y ment thereby. Y Y c Q; 2. The combination with a container for comprising a float chamber, a pivotallyinounted float in said '.chamber, a magnet, in connection with said floilt, an auxiliary chamber inclosing said i ma ct hermetically though in communica' 6 :tion-avith said float chamber, a second magl i net outside-of said auxiliary chamber but 'and indicating mechanism connected to said within the magnetic field of said first-named magnet for movement thereby, and an indicator connected to said outside magnet.

3. The combination with a float chamber, a

pivotally mounted float therein, an oscillating magnet connected thereto, an auxiliary chamber hermetically inclosing said magnet, 21 second magnet within the magnetic field of said first-named magnet, and indicating 7O mechanism connected to said secondmagnet:

4. lhe combination of a float chamber, a

5. The combination with a float chamber, of a float in said chamber, a pivoted magnet, an auxiliary chamber communicating with the float chamber and inclosing'the said magnet hermetically, an arm extending from I the pivotal portion of said magnet, a link I pivoted at its upper end to said arm, a float lever connected at one end to said float and; pivoted at its other end to the lower end of said-link, a fulcrum support for said float'lever within the float chamber, a second magnet outside and near said auxiliary chamber within the magnetic field of said first-named magnet for movement thereby,

outside magnet.

pivotally mounted float in saidchamber, a

movable magnet, means operatively connecta mg the magnet to the float, a chamber com- 9 municating with the float chamber and hermetically inclosing the magnet, a graduated dial, an indicator arm for the dial, a second magnet within the magnetic field of the first magnet and adapted to be moved thereby, a gear wheel-fixed to the second magnet, and a pinion fixed to the indi'riator arm and meshingwith the ear-wheel. i
